.in excess of the distance between the inner-V most scorlngv and theoutermost scoring ings, 3,3', a, 3'. and 4,. 4', 4", it may be said thatthe distance Vbetween the scor-V ings 3, and` and 3., 4-and 4", and 4vand 4 Vare all equal and that between, 3'

and 3' is equal to twice the dist-anoche tween anyl two adjacent otherscorings. Whilel have thus'indicated in theY draw-v l ing only threescoringsat 4 and four scor ingseat 3 it is possible to provide a greateror'less number of scorings in each set accordingto the degree ofeXpandbilityl de#L sired to be provided;'.but in any case, the

relative number andspacings of the. scorings in each set will vbedetermined bythe same principles followedin the ydistribution of `thescorings shown in the drawings,

lwhich principles willbe moreclearly set forth hereinafter, ,inVconnection with the explanation ofthe -manner inV whichtbe filing.cover is folded in order to provide for a large volume of contents.

Having described the construction of the filing coverfl will nowdescribethe mani Vner in which it is'folded for use. This dep'ends upon'thethickness of the contents thatV are to be placed lin the folder. If suchcontents are of inconsiderable thickfness, that is to say, of a verymuch less Vthickness tha-n the .distance between the 4 andjthe proximateauxiliaryscoring 4, the

y filingcover is 'simplyfolded at the scorings 4 `and 3,in the samedirection'at both scorings, with these'ction 7 folded overo'nly tov Y avery slight degree making a large obtuse angle with section 6, as shownin Figure 2.

The vfolder is inV this condition *ready yfor.

' the receipt of contents, such contents'being placed betweenlsectionsV74 5 and 56. The con-H tents having been placed into position,the

folds and are brought together until they arein close apposition to thecontents, and section 7 Vis thenifolded completelyY Sover,

Hso that thetab -l` passes intofthe aperture 2.y

The filing cover is now ready forpla'cing in the-file, being placed .cwith section7 either facing' the front orl the back of the-file (Incertain. filing installations it maybe found moredesirable `6 Vand maythen be readily consulted by mere'- tov place the folders inthe'dr'awer'with sec'.-

tion 7 facing'to the front ofthe drawer so. "that indexing or otherdescriptive material,

maybe inscribed for pasted upon such* foldly 'liftingthe foldup'withoutrin any way disturbing the body of thefolder, or lits conitents.)

Vthe cover isfolded in If 'contents to be placed in the tiling folderareY ofcmore than inconsiderable thickness. that isto say, if theylapproximate in thickness the distance between scorings 4 and 4", thetiling cover is folded in the following inannerrItisfolded as before onthe main scoring14, but in addition it is also folded, Y

von' scorings 4, 3 and 3, all folds being in the same direction. Figures3 and 4 show l perspective views of theV filing cover when thus folded.y. i n

Similarly if the Vcontents supposed to be placed in the filingY coverexceed in widthk the Adistance between scorings 4 and 4', Vthe Yscorings 4, 3 "and 3 areused, the base thusw having a widthv equal. tothe distance between `scorings 4 and 4" and the .topa

width equal to the distance betweenv scor`r ings 3 andi-3', andlbothy'widths being eq11a1? ,Y

. Iteismanifest that the iilingfolderherein described, suitablymodified, as to dimen-` sions, Vpositions of scoring, etc., to .meet

changing requirements, without however. changing `the underlyingprinciple, over comes all ofthe-objections set forth as pertaining toexisting forms of filing covers 'andis" at `the same time Vinexpensiveto pro-l duce, requiring only slightly more material l than Vthepresentfiling folder, and .involving no more labor in itsV production inquantity than does the present filingY folder,

inasmuch asall the scoring and cutting required can be Vperformed inioneoperation by the use of asingle die.

While I have herein shown anddescribed oneparticular embodiment of myinvention, I'wish it to be understoodk that I do susA not confinemyself'tfo ally the precise details of construction set'forth in theillustrations, as modifications an'dvariations may be made withoutdeparting from the spirit of the invention orzexceeding'thescope oftheappendedclaims. i Y
